Now, platform_get_boot_partition() will work correctly.

Now prints out a comment if LBA access doesn't work (since CHS access is not yet implemented).

Moved the data section closer to the end of the 1024 bytes of the boot
block - the region before is reused as scratch buffer in the real mode
data segment.

case it couldn't be used for booting (lack of a kernel or whatever).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7243 a95241bf-73f2-0310-859d-f6bbb57e9c96
was already correct, and my other source was wrong about it.

It switches to real mode for execution of the BIOS interrupt; it's really
only intended for the boot loader.

both Bochs and my real computer seem to know it anyway, so it's untested.
The real mode segment descriptors now start at 0x10000, because the code
is loaded there. Added an additional stack segment descriptor to be able
to use a stack below 0x10000.

gate, switch to protected mode, and will then jump to the platform dependent
loader initialization.
This is the start of the zbeos equivalent. It can already be executed
using the BFS boot block, but it cannot yet load itself from a floppy
like the original does.

network booting (for R1), and if we will, it will be done using another
mechanism anyway).
If it runs under Apple's OF implementation, it now adds ":0" as parameter
to the opened block device to bypass the disk-label package - that part
is obviously implementation specific (and took me some time to figure
out, even if it's just two characters ;-).
Added a commented block of code that could be used in combination with
MOL and it's (in the meantime fixed) broken device access via OF.

OpenFirmware client service calls (and callbacks).
Has nice inline argument getter methods If compiled under C++.

and idea about the underlying hardware (needed at other places).
Calls arch_set_callback() right after MMU takeover.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@5204 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added empty callbacks for "alloc-real-mem" and "unmap".
Implemented "map" and "translate" - the latter is not yet tested, though.

respective methods of their parent (one possible crash less, as the
nodes could get deleted accidently).
The AmigaFFS is now silent if it just don't know the signature.

was a load_kernel() call above). Added a comment that might prevent me from
doing that again...

Renamed AddNode() to AddVolume() - it's no longer virtual but private to
the root file system.
Added new method AddLink() to add a link to a volume.
The link handling is separate from the other volumes (to be able to iterate
only over real volumes). Added a name field to the inner entry class which
is used for links.

register_boot_file_system() adds the "boot" link to the root fs.
mount_all_file_systems() now prints out the root directory of the
mounted volumes just for fun (to be removed later).

- it will now successfully take over the MMU, but it doesn't tell OF
yet about it.
- map_page() will now fill in the page table relative to sSegments[], and
no longer to the segment registers directly (as they might be different
at that time, depending on the OF).
- map_page() will panic if it couldn't find a free slot in the page table
(that's enough for the boot loader)
- finds the exception handlers mapping and sets the kernel args
- rewrote insert_memory_range(); it now actually works in all cases (no
matter if the ranges overlap or not, and it will also join ranges if
possible). The start address will now be round down to page aligment.
- some other small fixes
- the page table is now cleared before use (as of_claim() obviously doesn't
return cleared memory).
- replaced some uint32 with addr_t where it made sense (there are probably
even more places).

Added new arch_mmu_free() function (not yet implemented).
